This article mainly introduces "what is the function of wan interface". In daily operation, I believe many people have doubts about what the function of wan interface is. The editor consulted all kinds of materials and sorted out simple and easy-to-use operation methods. I hope it will be helpful for you to answer the doubts about "what is the function of wan interface?" Next, please follow the editor to study!

The WAN port on the router is used to connect the external network (public network), or the equipment of the broadband operator; for example, the WAN port is used to connect the Moden (cat) when the telephone line is connected to the Internet; when the optical fiber is connected to the Internet, the WAN port is used to connect the optical cat; when the network cable is connected to the home network, the WAN port is used to connect the home network line.

The operating environment of this tutorial: windows7 system, Dell G3 computer.

The WAN port on the router is used to connect the external network (public network), or the equipment of the broadband operator. For example, when the telephone line is connected to the Internet, the WAN port is used to connect the Moden (cat); when the optical fiber is connected to the Internet, the WAN port is used to connect the optical cat; when the network cable enters the home to surf the Internet, the WAN port is used to connect the home network cable.

The WAN port of the router has three connection types, namely: PPPoE dialing (ADSL dialing, broadband dialing), dynamic IP (automatically obtaining IP address, DHCP), and 3, fixed IP (static IP).

The difference between LAN, WAN and WLAN interfaces on routers

1. WAN wide area Network (Wide Area Network), mainly used to connect external networks, such as ADSL, DDN, Ethernet and other access lines. To put it simply, it is the network port connected to the cat's external network.

2. LAN local area network (Local Area Network) interface, which is used to connect to the home internal network, mainly connected to the switch, hub or PC in the home network. To put it simply, it is the network port between the route and the user.

3. WLAN wireless local area network (Wireless LAN), the data is transmitted by electromagnetic wave, and the data is transmitted by radio frequency (RF) technology, so as to realize a smooth network with no network cable and no distance limit.

At this point, the study on "what is the function of the wan interface" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
